UNS Dual All-In-One 40A Aquarium – 17 Gallon Rimless Tank

The Ultum Nature Systems Dual All-In-One 40A Aquarium delivers the perfect combination of space, style, and performance. With a 17-gallon capacity, this model provides aquarists with more room for aquascaping creativity while maintaining the sleek rimless design and integrated triple-chamber filtration that make the UNS Dual AIO series stand out.

Crystal-Clear Rimless Display

The 40A is built from 91% clarity low-iron Diamant glass, with 45° precision-cut mitered edges and black silicone seams for maximum strength and elegance. Its cube layout creates a dramatic, balanced viewing experience, making it ideal for both compact reef systems and lush planted aquascapes.

Built-In Triple-Chamber Filtration

Designed for simplicity and efficiency, the 40A features a rear-mounted filtration system that keeps equipment hidden while maintaining crystal-clear water:

• Chamber 1: Mechanical sponge for removing debris and waste.

• Chamber 2: UNS Bio Bricks provide biological filtration for ecosystem stability.

• Chamber 3: Submersible pump with adjustable flow ensures reliable water movement.

This all-in-one system reduces clutter, making it easy to maintain healthy water conditions for both plants and livestock.

Freshwater & Saltwater Compatible
